Abstract
PURPOSE: To achieve noise reduction by setting the driving condition of a cooling fan of a radiator changeable to plural stages based on the parameters related to the operating conditions of an engine, and setting forcibly the cooling fan to the maximum capacity driving condition when the temperature of cooling water is kept above the predetermined high temperature for more than the predetermined time.
CONSTITUTION: A switching means M1 of the driving condition of a cooling fan is provided, which changes the driving condition of a cooling fan of a radiator to plural stages based on the parameters related to the operating conditions of an engine. A time counting means M2 for the high temperature condition is provided which measures the total consecutive time of excess in the condition when the temperature of cooling water exceeds the predetermined value. When the measured time obtained through the counting means M2 for the high temperature condition exceeds the predetermined value, the driving condition of the cooling fan is forcibly set to the maximum capacity driving condition irrespective of the above-mentioned parameters, then the switching means M1 of the cooling fan driving condition is controlled by means of the forced control means M3 of the maximum capacity driving so as to hold the maximum capacity driving condition until the temperature of cooling water becomes below the above-mentioned predetermined value of the high temperature.
